Electron microscope has a high resolution power. This is due to
Correct answer: B. Very low wavelength of electron beam
- A. Electromagnetic lenses
- B. Very low wavelength of electron beam
- C. Low wavelength of light source used
- D. High numerical aperture of glass lenses used.
Explanation
Factual Recall. Microscopes are used for studying cellular structures. They are used to magnify small objects. In electron microscopes, a high energy beam of electrons is focused through electromagnetic lenses. It can magnify very small details with high resolving power. The increased resolution results from the shorter wavelength of the electron beam.
